產(chǎn)品簡介

溫濕度變送器:公司是一家專業(yè)從事石油化工、船舶工業(yè)、污水處理、工程、醫(yī)藥食品等行業(yè)過程儀表及其自動化整體解決方案的民營高科技企業(yè)

詳細介紹

概述

summarize

WZPK溫度變送器是我公司推出的一款高性價產(chǎn)品，適用于多達十種的各型熱電偶和熱電阻信號變送。該產(chǎn)品使用24位Σ-△模擬前端，保證測量的高精度；的防浪涌、防反接設(shè)計，避免了工程應(yīng)用中的誤安裝和誤操作；增強的軟件安全設(shè)計，包括低壓監(jiān)控復(fù)位、多任務(wù)調(diào)度優(yōu)化等功能。WZPK全部采用進口元器件，保證較長的使用壽命和穩(wěn)定性。為了便于大客戶的長期備貨，可使用USB通訊線進行組態(tài)設(shè)置，并且設(shè)置時無需外接電源。

WZPK temperature transmitter is a high cost product from our company, suitable for up to ten types of thermocouple and thermal resistance signal transmission. The product uses a 24-bit Σ-△ analog front end to ensure high precision measurement. Perfect anti-surge and anti-reverse design to avoid misinstallation and misoperation in engineering applications; Enhanced software security design, including low-voltage monitoring reset, multi-task scheduling optimization and other functions. WZPK all use imported components to ensure long service life and stability. In order to facilitate the long-term stocking of large customers, the USB communication cable can be usedfor configuration Settings, and no external power supply is required for setting.

二、技術(shù)參數(shù)

三、接線方式

wiring mode

1號接線柱和2號接線柱分別為24V電源正負極，線路板帶防反接功能。

The No. 1 terminal and No. 2 terminal are respectively the positive and negative terminals of 24V power supply, and the circuit board has anti-reverse connection function.

LQT202接線圖

熱電阻連接支持二線制、三線。連接方式如上圖所示，實線為傳感器引出線，虛線為短接線，需要用戶自行用短導(dǎo)線連接（出廠時也可按客戶需要在內(nèi)部短接好）。

熱電偶正極連接3號接線柱，負極連接4號接線柱即可。

The thermal resistance connection supports two wire and three wire. The connection method is shown in the figure above. The solid line is the sensor leadout line, and the dashed line is the short wire, which needs to be connected by the user with a short wire (it can also be short-connected internally according to the customer's needs).

The positive terminal of the thermocouple is connected to terminal 3, and the negative terminal is connected to terminal 4.
